The U.S. Department of Energy notified American Transmission Co. that two ATC applications for smart grid investment grants totaling $12.7 million were selected for award negotiations. The grants are aimed at advancing smart grid technologies. There are 100 projects nationwide engaged in the same activity.[2]

American Transmission Company’s (ATC) Enhanced Supervisory Control and Data Acquisition (SCADA) and Phasor Measurement Unit (PMU) Communications Backbone project is deploying new fiber optic transmission communications infrastructure across the company’s Wisconsin footprint. The interconnection of the new fiber segments expands ATC’s data communications and integrates a total of 149 substations within ATC’s data communication and collection networks. Targeted benefits include improved communications reliability and reduced operations and maintenance costs.[3]
